there is one moment of crudeness
you could extend it to the flirtation before hand, but the bed scene lasts all of 30 seconds, with no nudity.and no fart jokes.
Profanity was very lean. To be honest, I don't remember any, but I tend to block it out unless it's a overblown. However, my wife, who is MUCH more sensitive to these things also remembers none. There's a lot of violence, but almost no blood, even in the operation scene.
On the whole, it's a very exciting film. The story, while predictable, really, was better than I was led to believe. It's very loyal to the feel and ideas of the comic. The acting and directing is superb.
And stay to the end of the credits. There's a bit at the end that is as revealing as the ending of X3, but much better written and directed. Also, not as questionable or foggy.
(and it has Samuel L. Jackson in the role I wish had been presented earlier in the film).
As far as Marvel movies go, this is on part with the first two spideys and X-Men films. It's almost enough to make you forget F4, Elektra, AND Daredevil.
I thoroughly enjoyed it.
